** Database constructor calling sequence, and Database::newFromParams()
** Including flags in the server initialisation structs
** Support for setting appropriate flags from legacy globals in Setup.php
** Moved some defines to Define.php so that they can be used in LocalSettings.php, most importantly the bit field constants
* Changes related to post-parse link colouring
** Turn the link cache back on when using it for updating the links table
** No longer need to call preFill() on page view
* Better synchronisation of slave servers
** Rearranged getConnection()
** System for beginning and committing transactions when multiple connections are open
** wfAbruptExit() commits transactions, wfErrorExit() does not. Various functions changed to use wfErrorAbort()
* Allowed reporting of database errors during deferred updates by moving them above output()
* DB_WRITE now called DB_MASTER, DB_READ now called DB_SLAVE
* Converted to use SQL wrapper functions instead of direct SQL in various places
* Experimental method for preserving the chronological order of events when slave servers are used. Untested.
* Fixes to the new post-parse existence test feature
* Some.. other stuff
This saves trouble in a number of places where we can now do joins with the link tables to get other info (such as cur_is_redirect!) as well as the name, and fewer bits need to be juggled on page renaming, as outgoing links no longer have to be changed (cur_id remains the same when a page is renamed).
rebuildLinks.inc and some of the tools in the 'maintenance page' still need to be updated to work with the new setup. (Special:Maintenance needs a *lot* of cleanup in general. It's kind of a catch-all of vaguely defined features which suck performance like a hydroelectric dam.)
Also I've slipped in some extra debug code. And, I think 'indexes.sql' is a big waste of time and should all be moved into tables.sql. Building indexes separately doesn't help on InnoDB and won't do anything on MyISAM either if you're just going to replace the table after it's built with an imported one from a dump which creates it with indexes.
* Converted many instances of globals from the query to $_REQUEST
* Renamed near-useless Title::getURL() to Title::getPartialURL()
* Created new Title::getURL(), to replace wfLocalUrl, wfLocalUrlE, wfFullUrl and wfFullUrlE. Replaced most instances throughout the code
* In Parser.php, generalised stripping of <nowiki>, <pre> and <math> to allow more general use such as nesting
* Moved body of Article::preSaveTransform to Parser.php
* Put lots of comments in Title.php
Installer is now able to connect to the db, check its version (and
enable some MySQL 4 features if available), create the database
if need be, create the empty tables, and grant user privs if given
the root pass. This creates a usable empty wiki.
TODO:
* Populate main page and stub log pages
* Create sysop account
* Populate MediaWiki namespace for selected language
* Better error checking
* Option for InnoDB tables?
* Other useful options like uploads and TeX (shudder)
* Support scripts still need to be checked for security.
Also fixed a minor bug in Database::tableExists which ran into infinite
loops if no tables were present, and made Database::selectDB modify
the right member variable.
To get around some problems induced by the new parser stuff, User
won't loadFromDatabase() if we're in CommandLineMode, since it ends
up trying to do so before we've set up the database and fails.
* Misc. bugs fixed in DatabaseFunctions.php and Skin.php.
* install-utils, install and update utilise Database objects instead of handling their own connections
* schema change for RC improvement -- added rc_type, rc_moved_to_title and rc_moved_to_ns
